“Hydrocephalus is a condition in which excess fluid builds up in your brain. The word hydrocephalus comes from the roots hydro meaning "water" and cephalus meaning "head." The fluid that accumulates is cerebrospinal fluid (CSF), a fluid that normally surrounds your brain and spinal cord.
In hydrocephalus, too much fluid builds up, causing abnormal enlargement of the cavities in the brain (ventricles) that contain CSF. Too much CSF in the ventricles can put too much pressure on the brain, potentially damaging the brain.”
